A multilayer radar-absorbing laminate includes three juxtaposed blocks. A first electrically conductive block is arranged toward the inside of the aircraft in use. A second electromagnetic intermediate absorber block has a layer of electrically non-conductive fiber sheets is permeated by graphene-based nanoplatelets to achieve a periodic and electromagnetically subresonant layer, the conductive layers containing graphene nanoplatelets alternating with non-conductive layers. A third block of electrically non-conductive material is arranged towards the outside and forms part of the outer surface of the aircraft. The second block is produced by depositing on the fiber sheets a suspension of graphene nanoplatelets in a polymeric mixture, with controlled penetration of the graphene nanoplatelets into the fiber sheets. A plurality of dry fiber sheets sprayed with the suspension of graphene nanoplatelets is superimposed. An unpolymerized thermosetting synthetic resin is infused into a lay-up made of the first, second and third blocks. Afterwards, the thermosetting resin is polymerized.
